Shot Blasting Machine in Shipyard Industry plays a crucial role in maintaining the quality, durability, and performance of marine structures. Shipyards deal with large steel plates, hull sections, decks, beams, and offshore components that are constantly exposed to moisture, saltwater, and corrosion. To ensure long-term protection, these components must be perfectly cleaned and prepared before welding, fabrication, or painting. Shot blasting machines help shipyards remove rust, mill scale, old paint, and contaminants while creating an ideal surface profile for strong coating adhesion. From roller conveyor shot blasting machines to plate priming lines and blast rooms, modern shipyards rely on high-efficiency blasting solutions to achieve SA 2.5–SA 3 surface finish and meet international marine standards. This makes shot blasting technology an essential part of the shipbuilding and ship repair industry.

Shot Blasting Machines in Shipyards: Complete Guide to Surface Preparation Solutions – SFEC India

Shipbuilding is one of the world’s most demanding industries, operating in harsh marine environments where corrosion, rust, scale, and contamination are constant challenges. From steel plates to ship hulls, pipelines to structural beams, every component used in a ship must undergo perfect surface preparation before welding, fabrication, painting, or coating. This is where Shot Blasting Machines in Shipyards play a critical role.

Today, modern shipyards rely heavily on advanced shot blasting technology to improve the life, quality, and performance of ship components. In this article, we will explore how different types of Shipyard Shot Blasting Machines, including Roller Conveyor Type, H-Beam Blasters, Plate Shot Blasting & Priming Lines, Blast Rooms, Pipe Blasting Machines, and more, are transforming the global shipbuilding and ship-repair industry.

This in-depth guide is specially written for industry professionals, engineers, and companies looking for efficient and high-performance surface preparation machinery—powered by SFEC India, a trusted name in the world of shot blasting and surface finishing solutions.

Why Shipyards Need Shot Blasting Machines?

Shipyards deal with massive steel structures that stay in direct contact with seawater, humidity, and chemicals. Shot blasting is essential because:

Removes Corrosion, Rust, and Mill Scale

Steel plates, hull sections, and frames get heavily corroded during storage and transport. Shot blasting restores a clean metal surface instantly.

Ensures Perfect Surface Profile for Coating

Marine paints, primers, and anti-corrosive coatings require a rough, anchor-like profile for strong adhesion.

Improves Welding and Fabrication Quality

Clean metal ensures defect-free welding and structural uniformity.

Extends Life of Ships and Offshore Structures

Shot blasting prepares the steel to withstand extreme marine environments for many years.

Increases Production Speed

Modern shipyards must produce large blocks quickly. Automatic machines help maintain consistent quality at high speed.

Because of these requirements, shipyards use large, heavy-duty blasting systems designed for continuous, long-duration operation.

Top Shot Blasting Machines Used in Shipyards

Shipyards require different machines depending on the size, shape, and function of components. Below are the most popular ones widely used across shipyards in India, Japan, Korea, UAE, Europe, and around the world.

Roller Conveyor Type Shot Blasting Machine

This is the backbone of shipyard surface preparation.

Used For:

• Large steel plates

• Ship building panels

• Flat steel sheets

• Fabrication components

Why Shipyards Prefer It:

• Continuous production

SFEC India designs heavy-duty conveyor blasters that meet the high-volume needs of modern shipyards.

H-Beam & Structural Shot Blasting Machine

Shipbuilding requires hundreds of structural elements like beams, stiffeners, ribs, and supports.

Used For:

• H-beams

• I-beams

• Channels, angles, plates, girders

• Large structural profiles

Advantages:

• Removes corrosion evenly

• Provides SA 2.5 surface cleanliness

• Supports both pre-fabrication & post-fabrication

For block fabrication yards, this machine is a must.

Plate Shot Blasting & Priming Line

This is the most advanced technology used in shipyards for mass steel plate treatment.

What It Does:

• Blasts steel plates

• Coats them with primer

• Fully dries the primer

• Ready for welding and assembly

Used For:

• Large marine fabrication projects

Why It’s Important:
Shipyards need ready-to-use, corrosion-proof plates. This machine guarantees long-term durability.

Pipe Shot Blasting Machine

Ships use hundreds of meters of pipes for fuel, water, hydraulic systems, and exhaust.

Used For:

• Internal pipe cleaning

• External rust removal

• Offshore pipelines

• Marine heavy-duty pipes

Pipe blasting ensures pipes are leak-proof, rust-free, and coating-ready.
